This is true for all semi/full auto guns, closed bolt guns, except the M9. They have a ultra secret unicorn scalloped extractor. This problem is compounded with MIM extractors. Want to ruin an extractor keep dropping it on a chambered round.
On an AR, the extractor has to snap over the case rim one way or another. The rim can't slip under it like a Glock or 1911 for example. It's not like the AR bolt can snap over the round in mid feed.
